public class Decomposer extends java.lang.Object implements EventIterator
The resulting sequence is decomposed, but not flat (it will contain nested EventIterators). To flatten
it, use EventStackIterator.flatten(EventIterator)
Constructor | Description |
---|---|
Decomposer(EventIterator base,
PipelineConfiguration pipe) |
Create a Decomposer, which turns an event sequence into fully decomposed form
|
Decomposer(NodeInfo node,
PipelineConfiguration pipe) |
Create a Decomposer which returns the sequence of events corresponding to
a particular node
|
Modifier and Type | Method | Description |
---|---|---|
boolean |
isFlatSequence() |
Determine whether the EventIterator returns a flat sequence of events, or whether it can return
nested event iterators
|
PullEvent |
next() |
Get the next event in the sequence
